In the eighteenth and nineteenth centuries hat makers were known as 'hatters'. At that time it Mercury was used in the hat making process, but mercury is very toxic and can cause illness which makes the sufferer appear crazy or 'mad'. So many hatters had mercury poisoning that the terms 'as mad as a hatter' and 'mad hatters' entered into common parlance.
The most commonly mined ore that yields a neurotoxin is cinnabar, which is a source of mercury. Historically, hat makers used mercury to make felt for hats, leading to mercury poisoning that caused symptoms similar to those of neurological disorders. This is where the phrase "mad as a hatter" originated from.

There is a commercial product called 'Dip It' for coffeemakers. Another method involves putting undiluted vinegar in the reservoir, plugging in just long enough for appliance to heat up, unplugging, allowing it to sit overnight...then empty it and wipe/scrub. my Rival steamer gave me grief today: I was trying to steam Tamales that were a Christmas gift. The steamer would shut off and come back on, shut off and come back on....I got mad and pitched it into the trash can, but I should go retrieve it and try the vinegar. if one routinely pours in a small amount of vinegar immediately after cooking, it prevents that build-up...but we can't seem to do this virtuously all the time. ;-)

The old hat making process involved intensive use of the element mercury (called quicksilver back in the day). Mercury fumes are incredibly toxic, and can cause severe neurological damage. The phrase mad as a hatter comes from how many hatters (hat makers) would die or go crazy at a young age due to mercury exposure from their work.

The Mad Hatters was created in 1935.
At one time hatters (the correct word for hat makers) used mercury in preparing the skins used to make hats and to get sharp corners in the hats they chewed on the skins. This caused ingestion of the mercury, which is a neurotoxin. They eventually developed mercury poisoning, which affected their brains causing a form of chemically induced madness.
